Answer:
Adsorption
Explanation:
Sidewalk cooking of egg is very popular in America. In summer people release fireworks in night sky and cook egg on the concrete sidewalk to check the level of temperature. When sunlight fall on the sidewalk most of the light is reflected back but some darker material adsorbs some photon, and when these photons are transferred to egg molecules it causes vibration among them and produce heat and cook egg.
Answer:
elastic collision
An elastic collision occurs when the two objects "bounce" apart when they collide. Two rubber balls are a good example. In an elastic collision, both momentum and kinetic energy are conserved. Almost no energy is lost to sound, heat, or deformation.

The distance of the image formed is 44.27 cm and the magnification of the image is 0.7.
<h3>Location of the image</h3>
The image distance formed by the lens is calculated as follows;
1/v + 1/u = -1/f
where;
- v is the image distance
- u is the object distance
- f is the focal length of the lens
1/v = -1/f - 1/u
1/v = -(-1/26) - 1/63
1/v = 1/26 - 1/63
1/v = 0.022588
v = 1/0.022588
v = 44.27 cm
<h3>What is magnification of lens?</h3>
The magnification of a lens is defined as the ratio of the height of an image to the height of an object.
<h3>Magnification of the image formed</h3>
The magnification of the image is calculated as follows;
Magnification = image distance/object distance
M = 44.27/63
M = 0.7
Thus, the distance of the image formed is 44.27 cm and the magnification of the image is 0.7.

Answer:
It was most likely static electricity
Explanation:
Static electricity comes down to the interactive force between electrical charges.
So because your computer charger has electricity the foil is a conductor so the sparks were most likely static electricity
